    Background: Orofacial clefts are the most common malformations of the head and neck region. Genetic and environmental factors have been implicated in the etiology of these traits. Methods: We recently conducted genotyping of individuals from the African population using the multiethnic genotyping array (MEGA) to identify common genetic variation associated with nonsyndromic orofacial clefts. The data cleaning of this dataset allowed for screening of annotated sex versus genetic sex, confir mation of identify by descent and identification of large chromosomal anomalies. Results: We identified the first reported orofacial cleft case associated with pater nal uniparental disomy (patUPD) on chromosome 22. We also identified a denovo deletion on chromosome 18. In addition to chromosomal anomalies, we identified cases with molecular karyotypes suggesting Klinefelter syndrome, Turner syndrome and Triple X syndrome. Conclusion: Observations from our study support the need for genetic testing when clinically indicated in order to exclude chromosomal anomalies associated with clefting. The identification of these chromosomal anomalies and sex aneu ploidies is important in genetic counseling for families that are at risk. Clinicians should share any identified genetic findings and place them in context for the families during routine clinical visits and evaluations.

    ILLNESS BEHAVIOUR AND UTILIZATION OF ORAL HEALTH CARE FACILITIES AMONG TRADERS IN MUSHIN MARKET
    (Unilag Journal of Medicine, Science and Technology (UJMST), 2019) Olu-Awe OI1, Dedeke AA, Alade OT, Uti OG, Sofola OO
    Maintenance of good oral hygiene is of paramount importance to oral health, this is due to the fact that oral health is a mirror of overall health and well-being. The use of available oral health facilities is a step in the right direction. The aim of this study was to assess the knowledge, level of utilization, and illness behavior of traders in Mushin market towards use of oral health care facilities. Cross-sectional study comprised of 300 adults traders with stalls in Mushin market. Data was collected using a structured interviewer administered questionnaire, with segments on sociodemographic characteristics, knowledge, level of utilization, and illness behavior towards the use of oral health care facilities. Data was analyzed using Epi-Info, version 7. Test of association was assessed using Chi-square test (P=0.05). A total of 300 adults participated in this study with a mean age of 37.7±12.1. Two hundred and eleven (70.3%) were females, two hundred and sixty one (87.3%) had a good level of knowledge of oral health care facilities. Only ten (3.3%) respondents had any significant level of dental health facility utilization, 90 % had poor illness behaviours as regards oral healthcare. Although most respondent had a good knowledge of dental health facilities in close proximity and availability of dental services, most sought treatment in numerous places apart from the dental clinic

    The impact of playing wind musical instruments on the dental arch dimensions in a male west african population
    (Wolters Kluwer ‑ Medknow, 2020) Tayo Emmanuel, Adeyemi; Olayinka Donald Otuyemi
    Background: Dental arch dimensions are important considerations in orthodontic treatment planning and monitoring. Objective: This study aimed to compare the dental arch dimensions in wind and non‑wind instrument players (WIP and non‑WIP). Methods: This was a cross‑sectional study which compared a group of 50 male subjects aged 18–45 years that had been playing wind instruments for a minimum of 2 years with a control group matched for age in the same environment. The arch dimensions were assessed for both groups by measuring their dental casts using a digital caliper. Data was analyzed using statistical Software Package for Social Sciences (SPSS Inc, Chicago, IL) version 17. Statistical significance level was set at P < 0.05. Results: The mean number of years of playing wind instrument among the WIP was 9.26 ± 6.21 years. All the maxillary arch dimensions were larger in the WIP group except for the palatal depth while the mandibular arch parameters in the non‑WIP group were larger than the WIP group except the mandibular arch length. The differences were not statistically significant (P > 0.05). The mean maxillary inter‑canine width (37.48 ± 1.12 mm), inter‑molar width (57.27 ± 1.99 mm), arch length (29.80 ± 2.2.09 mm), and palatal depth (22.21 ± 2.33 mm) for class B instrument (Saxophone and clarinet) players were larger than either the class A instrument (Trumpet and trombone) players or the non‑WIP group. These differences were not statistically significant (P > 0.05). Conclusions: Playing a wind instrument as well as the type of instrument played, duration, and frequency of play did not significantly affect dental arch dimensions

    Prevalence and Distribution of Cracked Posterior Teeth among Adult Patients
    (Scientific Research Publishing, 2020) Temiloluwa Olawale Ogundare; Deborah Mojirade Ajayi; Paul Ikhodaro Idon; Cornelius Tokunbo Bamise; Adeleke Oke Oginni; Temitope Ayodeji Esan
    Background: There are challenges in detection and prevalence of cracked teeth, especially in asymptomatic cases. This underestimates the actual prevalence and possibility of preventive restorative treatment. Objectives: To determine the prevalence and distribution of cracked posterior teeth among adult patients attending the dental clinic of OAUTHC, Ile-Ife, Osun State, Nigeria. Materials and Methods: A cross sectional study where consecutive patients aged 18 years and above were examined for the presence of cracked posterior teeth over a period of one year (May 2016-April 2017). The teeth were initially examined with the naked eye. Thereafter, transillumination, methylene blue dye and magnifying lens were used to aid detection of more cracks. Data was analyzed with the IBM Statistical Package for Social Sciences (SPSS) for Windows (version 21.0). Level of significance was set at p ≤ 0.05. Results: Out of the 64,370 posterior teeth examined for cracks in 3345 patients, 264 were diagnosed as cracked in 152 patients, giving a patient prevalence of 4.5% and tooth prevalence of 0.4%. Amongst the 152 patients, the prevalence was 9.1%. There was a slightly higher male preponderance while cracked tooth was observed to increase with age (p = 0.007). The skilled (56.6%) and those that attained tertiary education (77.6%, p = 0.023) had more cracked teeth. Mandibular first molar (19.7%) was the most frequently cracked tooth type. The cracks were usually centrally placed (91.7%) and run in a mesiodistal direction (61%). Transillumination (44.7%) detected more cracked teeth. Conclusion: Prevalence of cracked tooth was observed to be low with a slightly higher proportion in male and the figure increases with age. Mandibular first molar was the most frequently cracked tooth while transillumination was the most useful diagnostic tool. Most cracks ran in the mesiodistal direction and fracture lines were usually centrally placed.
